Frequently, that is certainly telling you that there's a issue while in the transfer scenario — trouble codes need to be set, so have your car scanned by your mechanic. I have no experience While using the 4WD company light, so besides that, I have no additional facts.
I really don’t possess the practical experience to say definitively yes, or no — but I would like you the best of luck. Please, let's know how you make out.
That’s odd that the light will occur on immediately, without having flashing and without engaging the 4WD. The reliable gentle approaching at 4Hi is frequently an indication the technique is purposeful.
For those who hear clicking likely into 4Lo, although not popping out (to 2Hi or 4Hi), then You may additionally Use a lousy relay inside the TCCM. Substitution with the TCCM is going to be needed (Except you wish to get it to an electronics male who might be able to substitute the relay for you).

If there's no connector, like I explain, Then you really will have to have One more set of schematics, and an individual accustomed to that system.
I don’t want to provide you with negative news, but I'd personally suspect the latter as the lights will usually flash while the system is trying to engage 4WD, regardless of whether it doesn’t engage, the lights flash whilst it’s striving. If your lights don’t flash, that tells me the procedure isn’t even trying to have interaction 4WD — and that’s controlled from the TCCM.
